Hi girls) I need advice on how to wean a 10-month-old from breastfeeding... There are no daytime feedings, only at night. I'm pregnant right now and I have no milk at all. If I had milk I'd still be nursing. But he sucks like a pacifier. I'm not sleeping at all and my breasts hurt. He won't take a bottle at all. I bought a sippy cup — at least he's started drinking tea from it. I put him to bed at night with grandma and I don't have any other methods.
